SPRING.

Application. filed November 27, 1922.

T 0 aZZ whom it wmy concern:

Be it known that I, Enwi'n Ewiivs, a citizen of the United States. residing at Clinton, Iowa, have invented certain. new and seful Improvements in Springs, of which the following is a specification.

My present invention relates to springs such as are more commonly used as bed springs, but capable of use also in certain upholstered furniture ant. in other like situations. Among the objects of my invention are to improve upon existing constructions of the character referrer. to; to produce a stay spring for a structure of he character mentioned, which will be ea y and economical to manufacture, and which will require a minimum of labor for attachment to the main springs; to produce a stay spring which will have a wide bearing on the main spring to which it is secured so that lateral rocking thereof will be minimized, and one which when applied in operative position to the main spring will not become acciden tally disconnected therefrom, but can be removed therefrom when desired; and such further objects, advantages and capabilities as will later more fully appear.

My invention further resides in the com: bination, construction and arrangement of parts illustrated in the accompanying drawing, and, while I have shown therein a pre ferred embodiment, I desire the same to be understood as illustrative only and not as limiting my invention.

In the annexed drawing Fig. 1 is a fragmentary plan view of structure embodying my present improvements.

Fig. 2 is a broken perspective view showing in detail my invention.

Fig. 3 is a fragmentary elevation illustrating the present improvements.

Referring more in detail to the annexed drawing, numeral 1 designates a plurality of main springs connected by crossed springs 2, which are preferably, though not necessarily. intertwined as is common in this art. Each of the main, body or supporting springs 1 has a terminal coil 3 to which the stay or brace springs are secured under sufficient tension to prevent them from becoming laterally detached. Stay springs 2 are axially expansible spirals provided at each end with a double hook, both parts of which engage the coil 3 so as to give a wide bearing supporting contact be- Serial No. 603,419.

tween the parts so that relative rocking between connected springs will be nized.

lit will be observed f-om an errainination of Fig. 2 that the terminal coil of a spring is bent outwardly at l, upwardly at 5, inwardly at G, laterally at '1 outwardly at downwardly at 9.. inwardly at 10, laterally at 11. and o'utwz dly at 12, so that a two armed or double hook is formed at 5 and 9 which is integral with spring 2. The upper and lower portions of this spring are in sufficiently clos contact with the coil 3 to p event any great amount of relative rocking between the parts. This is materially assisted by the wide spread between the parts 5 and 9. The lips 7 and 11 are sufficiently close together to require a pressure to force one side of coil 3 into the bight therebetweemand when inserted to prevent a too easy removal therefrom. As a r sult of this structure the stay or brace springs 2 will not become accidentally disconnected from the main springs during handling or usage. Inasmuch as these springs are made entirely by machinery, the amount of manual labor involved is reduced to a minimum since all the work that must be done by the operator in assembling is to take a pair of intertwined springs 2 and hook their re- 35 spective ends upon the proper coil 3 of the adjacent springs 1.

It is understood that the specific description of structure set forth above may be departed from without departing from the spirit of my invention as set forth in this specification and the appended claims.

Having now described my invention, I claim:

1. In a structure of the character described, having a series of coiled upholstery springs, a brace spring connecting two of said series of springs, said brace spring having a terminal coil bent to form a double hook, the upper and lower portions of the hook being sufficiently close together so that force must be used to cause a coil. of the upholstery spring to pass therebetween, and the loose end of the brace spring cooperating with the terminal coil of the brace spring to facilitate insertion of a coil of an upholstery spring into the hook.

2. A brace spring for connecting upholstery springs, comprising a terminal coil bent to form an upper hook and an under hook, the bend of said upper hook extending into the bend of the lower hook to form a closed bight between the hooks for holding the coil of the upholstery spring in said bight between said hooks, said hooks being resilient to flex when the coil of the upholstery spring is forced between said hooks and being normally close together to prevent the disengagement oi the upholstery spring coil from the hooks except by applied force.

3. A brace spring for connecting upholstery springs, comprising a terminal coil bent to form an upper hook and an under hook, the bend of said upper hook extending into the bend of the lower hook to form a closed bight between the hooks for holding the coil of the upholstery spring in said bight between said hooks, said hooks being resilient to flex when the coil of the upholstery spring is forced between said hooks and being normally close together to prevent the disengagement of the upholstery spring coil from the hooks except by applied force, said brace spring having a coil so spaced from said under hook for guiding the coil of said upholstery spring to the end of the under hook and holding the latter coil in place when force is applied for facilitating the entry of said latter coil into the bight between the hooks.

l. A brace spring for connecting upholstery springs, comprising a terminal coil bent to form an upper hook and an under hook, the bend of said upper hook extending into the bend of the lower hook to term a closed bight between the hooks for holding the coil of the upholstery spring in said bight between said hooks, said hooks being resilient to flex when the coil of the upholstery spring is forced between said hooks and being normally close together to prevent the disengagement of the upholstery spring coil from the hooks except by applied force, said hooks having laterally spaced loops through which the coil oi? the upholstery spring passes, said loops forming the rear or closed end of the bight between said hooks.

In witness whereof, l hereunto subscribe my name to this specification in the presence of two witnesses.
